What is Heat? (Thermal Physics)

The concept of Heat (noted Q) is central to many areas of physics: thermodynamics and thermal physics of course, but also astrophysics, materials science, engineering and many more. It is heavily used also in other subjects like chemistry, biology, geology etc.

In this video, you will discover what heat is exactly: a non-mechanical transfer of energy from a hot object to a cold object. This is why, in the first section of the video, a precise definition of temperature is provided. Then, the concept of heat is detailed by looking in detail what happens at the contact-interface between two solids at different temperatures.
